DOOR STRAIGHTENING TOOL Filed Nov. 4, 7 1929 A itorney Patented July 22, 1930 ENT; FF CE WILLIAM s. BRYAN, or RICHMOND, VIRGINIA DOOR-STRAIGHTENING TOOL Application filed November 4, 1929. Serial N6. 404,757.

Thisinvention relates to door straightening tools and more partic ularly to tools of this character which are especially adapted for use in straightening the doors of automobiles but it is to be understood that atool constructed in accordance with this invenit is found adapted.

An important object of the invention is to provide, in a manner as hereinafter set forth,

a door straightening tool of the aforemen tioned charactenwhich is adapted to be exlongitudinally on the supporting beam or bar 2 in a manner to apply'pressure to thedoor upon which the device is mounted at various points Within the longitudinal length thereof.

Other objects of the invention are to provide a door straightening tool of the character set forth which will be simple in construction, strong, durable, efficient in its use and which may bemanufactured at low cost.

Other objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein 7 g Figure 1 is a side elevation of a door straightening tool constructed in accordance with this invention showing the same mounted in position on a door, the latter being shown in dotted lines.

Figure 4 is an enlarged detail view in front elevation ofthe longitudinally adjustable door engaging hook which is mounted on the lower end of the tool.

view in front reference character 1 designates an elongated bar' or beam which is longitudinally split intermediate its end to provide.the spaced parallel side portion 2which provides the elongated longitudinal slot 3 in said beam.

The upperportion of the beam 11s twisted tion may be utilized in any manner for wh ch at right angles, as .1124, and is provided with a horizontally disposed forwardlydirected shankor extension 5 which terminates in a down-turned doorengaging hook portion 6 which engages over the upper-portion of the "door, shown in dotted linesin the drawings and designated by the referen ce character 7.

The inner face ofthe hook 6, at its upper end,

is beveled as at 8 and secured to the inner face of said hook through the medium of the securing elements 9, is a pad 10fwhich ex: tends below the hook 6 and hasits lower portion extending forwardlyat an obtuse angle,

A door engaging hook 11 is. mounted for? vertical longitudinal adjustment on the beam 1 through the medium of the slotted shank or arm 12 through which said beam extends, The arm 12 fits somewhat loosely about the, beam 1 andis held in adjusted position thereon by frictional engagement therewithwhen pressure is applied to thehook 11 as will be apparent. -A stop bolt 13 extends trans-' versely through the lower end portion of "they beam 1 for preventing removalof the hook' i 11 therefrom; The free end of the hook 11 is turned outwardly as at 14 and secured to end portion illustrated in Figure 1 of'the drawing.

'A rectangular collar 18 encircles the split 7 portion 2 of the beam 1 and is mounted for longitudinal movement thereon. The forward side of the collar 18 is provided with anjinwardly extending neck.19 which extends into the slot 3 andsaid neck andfthe adjacent portion of the collar are providedgwith aligned internally threaded bores for thread ed engagement with a pressure screw 20 which extends through saidi'slot 3 and projects through an opening 21in the opposite I V fsideofthe1collar'1 8. Said opening 2lisof Referring to the drawings in detail, the

theinner face thereofthrough the medium of the securing element 16, isthe cushioning 'pad 17 having the forwardly'turnedupper At its forward end, the pressure screw has swivelled thereon a work engaging head 22 and the opposite end of the pressure screw is provided with an actuating crank 23.

In the use of the tool, the upper hook is engaged over the upper end of the door and the lower hook is adjusted longitudinally on the beam 1 and engaged under the lower end of the door. The pressure screw 20 is then adjusted to the desired point on the beam through the medium of the'slidable collar 18 and is then screwed forwardly into engagement with the door with the obvious result that the intermediate portion of the door will be forced forwardly and the opposite end 7 thereof will be held stationary or drawn rearwardly, as will be apparent. The cushioning pads on the door engaging hook will prevent marring or damaging of thedoor. 7 The adj ustability of the pressure screw 20 permits the application ofjpressure of different points on the door without the necessityof removing the tool therefrom.

It is believed that the manyadvantages of a straightening tool constructed in accord ance with this invention will be readily understood, and although the preferred embodi- V ment of the invention is as illustrated and described, .it is to be understood that changes in the details of. construction may be had which will fall within the scope of the invention as claimed.

What is claimed is 1. A door straightening'tool of the character described comprising an elongated beam having a split intermediate portion providing an elongated longitudinal slot, a rectangular collar encircling the split portion and adapted 'for longitudinal movement thereover, a

door engaging pressure screw threaded through the collar and extending through the 7 slot and adapted 'to travel longitudinally I therein, an actuating crank on one end of the pressure screw, a forwardly and inwardly extending door engaging hook integrally I formed on one end of the beam, a forwardly opening in the neck and in the opposite side of the collar, a pressure screw extending through the unthreaded opening and threaded through the neck and the threaded opening, a door engaging head swivelly mounted on the forward end of the pressure screw, an actuating crank on the opposite end of the pressure screw, said pressure screw adapted to travel longitudinally through the slot in the beam, an integral door engaging hook extending forwardlyand inwardly from the upper end of the beam, a forwardly andinwardly extending door engaging hook slidably mounted for longitudinal adjustment on the lower portion of the beam, means for retaining the last named hook on the beam, and cushioning pads mounted on the inturned portions of the hooks, j

In testimony whereof I aflix my si nature.
